Detektivové z Tajemné ulice: Záhada ztracené brože – Guzowská Marta (2021)

When Hanka meets Péťa, his sister Anďa, and the rat Sherlock in the elevator, nothing suggests that they are about to experience something special that afternoon. However, during a visit to Péťa's and Anďa's grandmother, it becomes clear that a detective will be needed. Or rather, three. A brooch has gone missing – an important family heirloom, a copy of a jewel belonging to Duchess Izabela Czartoryska. That day, only the neighbor Mrs. Hela, the postman, and a television repairman entered the grandmother's apartment. Who among them stole the precious cameo? The series Detectives from Mysterious Street combines an adventurous story with interesting historical facts and presents it in an entertaining, interactive form. The reader is drawn into the plot through puzzles and forced to think logically. The book is intended for children aged 7 and up.
